166D.9 QUARANTINED HERDS.
1. Swine which are part of a quarantined herd shall only be moved
by restricted movement in accordance with section 166D.10A.
2. A herd shall be released from quarantine when no animal,
including livestock, on the premises shows clinical symptoms of
pseudorabies. In addition one of the following must occur:
a. The swine have been removed from the premises, and the
premises have been cleaned and disinfected under supervision of the
department or the inspection service. The disinfectant shall be
approved by the department or inspection service. The premises must
have been maintained free of swine for thirty days. However, the
epidemiologist for good cause may determine that premises shall be
maintained free of swine for a period greater or less than thirty
days.
b. Swine reacting positively to a test have been removed from
the premises. Remaining swine, except suckling pigs, must be tested
and react negatively to the test thirty days or more after removal of
the herd's swine reacting positively to the test.
c. The swine reacting positively to a test have been removed
from the premises. At least thirty days after removal of the
positive swine, breeding swine remaining plus a random sample
equaling twenty-eight of grower-finishing swine more than two months
of age must react negatively to the test. While the state is in
stage III or IV of the national pseudorabies program pursuant to
federal regulations, the grower-finisher swine must react negatively
to a test at least thirty days after reacting negatively to the last
test.
3. a. While the state is classified in stage I, II, or III of
the national pseudorabies program pursuant to federal regulations,
the following requirements must be satisfied:
(1) All swine present on the date the quarantine was imposed have
been removed.
(2) There must have been no clinical signs of pseudorabies in the
herd for at least six months.
(3) The epidemiologist must either conduct two successive
statistical samplings at least ninety days apart, or conduct
statistical samplings according to rules adopted by the department
which are consistent with the national pseudorabies eradication
program, which reveal no infection within the new breeding swine.
(4) The epidemiologist must either conduct two successive
statistical samplings ninety days apart, or conduct statistical
samplings according to rules adopted by the department which are
consistent with the national pseudorabies eradication program, which
reveal no infection in the herd's progeny at least four months of
age.
b. A herd removed from quarantine under this subsection shall
be tested by statistical sampling one year later, unless an
epidemiologist determines that the herd must be tested earlier. Section History: Recent Form
